JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Build a Quiz Challenge, Part 1 Solution

My questions are both strings and numbers.

Hi,

My questions array, I have both strings and numbers as answers:

var questions = [ ['Whats the capital of England?','LONDON'], ['How many days in a week?',7], ['Where is Michael Schumacher from?','GERMANY'], ['Capital of Japan?','TOKYO'] ];

I have my response var as

response = parseInt(prompt(question).toUpperCase());

The parseInt deals with the numbers, and the toUpperCase puts it in to uppercase, not surprisingly. Do I need to do an if statement if response is a string or number?

Thanks

Hi Tom,

In this case, if you are not going to do a mathematical operation with the users response than it is okay to leave out the parseInt(). Wrapping the prompt() with a parseInt will return a 'NaN'.
